MACHiNE FOR TURNING FLAT-SIDED OBJECTS.

SPECIFICATION forming part of Letters Patent No. 236,079, dated December28, 1880. Application filed October 22, 1880. (No model.)

To all whom it may concern:

Be it known that I, CARL PREUss, of the city of Berlin,-in the Kingdomof Prussia and Empire of Germany, have invented a certain new and usefulImprovement in Machines for Turning Flat-Sided Objects, of which thefollowing is a specification.

The purpose of my invention is to produce a machine for turning flatsided objects,

which can be readily adjusted for holding objects of different length,and in which the objects can be secured to and removed from the machineseparately and will be firmly held in position, so as to be incapable ofdisarrangement while the cutting is being performed.

My invention consists in the peculiar novel devices employed by me forthis purpose, as fully hereinafter explained, and pointed out by theclaims.

In the accompanying drawings, forming a part hereof, Figure l is a sideelevation of the machine with one baluster in position; Fig. 2, an endview of the machine, one of the holding-disks being removed and twelvebalusters being shown as secured to the remaining disk; Fig.3, avertical central section of one holding-disk, and Fig. 4 a faceview ofthe clamping-plate.

Like letters denote corresponding parts in all the figures.

The parts of the machine are mounted on a shaft, a, which may be heldbetween centers or-journaled in suitable boxes.

Large disks, b b, are fixed adjustably upon 5 the shaft to by means ofkeys 0 sliding in seats 0 cut in the shaft, and held in the disks byupturned ends and set-screws d, which turn through the hubs of the disksand force the keys against their seats. Each disk has a 0 flange, c, onits inner side, whose periphery is polygonal in shape. These flangeshave a number of flat surfaces equal to the number of balusters or otherflat-sided objects that can be turned at one time, the flat surfaces ofthe two disks being arranged opposite each other.

To the peripheries of the disks are secured toothed clamping-plates 9,(one for each flat surface of the flanges 0,) which are held by go nutsand bolts h, and project beyond the inner sides of the disk.

The disks are arranged the proper distance apart to receive between themthe objects to be turned, and are then rigidly secured to the shaft. Theblanks f are then placed on the flat surfaces of the flanges c, and areclamped in position by the plates 9. All the surfaces of the flanges care thus filled, and the blanks form a cylinder, being parallel with theshaft a, and having their outer surfaces arranged at right angles toradial lines.

A pattern for cutting by may be secured to one of the blanks.

The shaft 0, being revolved, one side of the blanks is cut to thedesired shape. All the blanks except one are then turned so as topresent another side outward,'the blank not turned serving as a guide toform the others by. This operation is repeated until all sides of theobjects are shaped, when they are removed from the machine and a new setof blanks put in their place.

The disks, it will be seen, can be adjusted to accommodate objects ofany length.

Objects having four sides, or any greater even number of sides, can beturned on the machine.

If it is desired to turn objects having three, five, or any other oddnumber of sides, the seats on the flanges 0 can be made to receive anyangle instead of the flat side of each object.

By having seats on the disks of the shape of the ends of the objectsthey can be rigidly held, so that there can be no displacement incutting. The objects being held by separate clamping-plates, they can besecured to and removed from the machine separately, and can be moreconveniently handled and more accurately arranged than when a singleclainping- 0 ring is used to secure each end of all the objects. Themeans for holding the disks to the shaft permit of a ready adjustment ofsuch disks, and at the same time prevent the shifting of the disksaxially on the shaft, the seats 5 of each pair being always kept exactlyopposite each other.

What I claim as my invention is- 1. In a machine for turningflat-sidedobjects, the combination, with the shaft to, of the I00 disks1), adjustable thereon, and having flanges 0, provided with flat seatsfor receiving the ends of the objects, and the clamping-plates structcdand arranged substantially as de- 10 g, one for each of said seats,substantially as scribed and shown. described and shown.
